Re: [Po4a-devel] Translatable attributes in HTML

Recently I've started to play with po4a while trying to internationalize a bunch of articles in HTML format. One of the major obstacles for making the job done is this: po4a considers as translatable (almost) only the text contained between the tags of an element. This is OK, but sometimes is not enough, since in HTML some attributes are intended to contain a human-readable text. For example: <link rel="stylesheet" type="text/css" href="/new.css" title= "All-new style of mine"> <a href="/" accesskey="1" title="Go to the project homepage"> The value of the `title' attribute here should be translatable too. In fact, HTML.pm already does this by treating the IMG's `alt' attribute specially and thus making it's value translatable. Maybe IMG's `alt' is the most common case for an attribute that needs translation, but there are three other elements that also can contain `alt': INPUT, AREA and APPLET. They deserve the same treatment as IMG. Also, it would be nice if `title' attribute is considered translatable too (keeping in mind that any element can contain a `title' attribute). A patch that solves those two problems is attached.
